COKE-CH'UTE.

SPECIFICATION forming part of Letters Patent No. 410,005, dated August 27, 1889.

Application filed April 29, 1889. Serial No. 309,066- .(No model.)

1 To all whom it may concern:

' chute or to the passage-way leading to the regenerative furnace, in which a part of the coke from the retorts is received and used.

It is my further purpose to provide a simple and inexpensive'device whereby the coke as it is drawn may be either guided without the direct manipulation of the operative to the furnace-chute, or when the drawn coke is in excess of the requirements of the furnace be directed to an opening leading to the cokecellar.

The invention consists in the several novel features of construction and new combinations of parts hereinafter described and claimed.

Referring to the accompanying drawings, Figure 1 is a front elevation of a gas-bench, showing my invention applied thereto. Fig. 2 is a detail elevation showing the coke-chute, together with a portion of the-furnace-chute, the latter shown in dotted lines. Fig. 3 is a plan view of the coke-chute shown in Fig. 2. Fig. 4 is a front elevation of the cokechute shown in Figs. 2 and 3, showing the side thrown down. Fig. 5 is a central longitudinal section of the coke-chute, showing the pivoted flooring-piece of the latter turned up into the position to form in conjunction with the sides of the chute a hopper, whereby the coke may be diverted either into the furnace-chute or into the openings leading to the coke-cellar.

In the said drawings, the reference-numeral 1 designates a gas-bench having retorts 2 of any known construction usual in this class of apparatus.

Centrally arranged relatively to the gasbench is a chute 3, formed of any suitable metal, which is permanently mounted upon a foot-piece 4 at one end, and which rests at its other end upon the horizontal portion 5 of the gas-bench, its point being contiguous to an opening 6 in said bench, whereby if no obin g in the bench and conveyed to the coke-cel-.

lar or receptacle beneath, where it is quenched by water and thence removed and sold.

The chute 3 consists of a trough-shaped conveyer, as shown in Figs. 2,3, 4, and 5,11aving sides 7, which may slightly converge from the higher toward the lower end of the chute. The side wall of the chute adjacent to the furnace is cut away to form a segmental opening 8, to cause thechute to conform to the shape of the mouth-piece of the retort and permit its edge to be placed close up under the flange surrounding the door. The front wall 7 is hinged upon the body portion of the chute, as shown in Fig. 2, to permit the door of the retort to be opened, said wall being fastened in normal position by a catch or latch 9, of any suitable form, pivoted on the end plate of the chute and hooking over a pintle 10, projecting beyond the end of the hinged wall 7, as shown in Figs. 2, 3, and 4. p

In the floor 12 of the chute 3 is formed an opening 13, of any desired form and size, and between the walls 7 is p'ivotally mounted'a hopper-plate 14, which may be turned into opposite angular relations with the bottom or floor 12 to cover the opening 13, or, on the other hand, may be turned into the position shown in dotted lines in Fig. 5, in which position said plate forms, in conjunction with the parts to which it-isconnected, a hopper and chute or conveyer combined forthe coke from the central series of ovens to the furnace-chute. Should this supply prove to be excessive, the hopper-plate 14 may be thrown over to form an opposite angle with the hopper-bottom, in which position it covers the opening over the furnace-chute, and the coke is thereby diverted through theopening 6, whence it passes to the coke-cellar below, where it is quenched and thence carted away and sold.

The invention provides a simple and inexpensive means of feeding the furnace and disposing the surplus coke with economy of time and labor and with great promotion of convenience to the workman, since no direct manipulation is required to guide the red or glowing coke to the furnace and coke-cellar.

hat I claim as my invention is 1. The combination, with a gas-bench having an opening leading to the furnace-chute and another opening leading to the coke-cellar, of a coke-chute located beneath the retortdoors and over the furnace-chute, said cokechute having a hopper-plate hinged in its bottom and the chute being arranged over the furnace chute, with its lower end in contiguity to the opening leading to the coke-cellar, substantially as described.

2. In a gas-bench, the combination, with a series of retorts, of a coke-chute consisting of a bottom having a discharge-opening and two converging sides, one of which is hinged to turn outward, and a hopper-plate hinged upon the bottom of the chute and adapted to be turned in opposite directions to form an angle therewith to direct the coke from the retort-s through the discharge-opening int-0 the I furnace-chute or through the side opening into the coke-cellar, substantially as described.

3. In a gas-bench, a coke-chute arranged over the furnace-chute and beneath one or more of the retorts, said coke-chute having an opening in its bottom over the furnacechute, and a bottom plate adapted to either close said opening or to be used to form in conjunction with the chute a hopper to guide the coke to said opening, substantially as described.

4. In a gas-bench, a coke-chute arranged over the furnace-chute and provided with a hinged front wall and an opening in the bottom above the furnace-chute, in combination with a reversible bottom plat-e, substantially as described.

In testimony whereof I have affixed my signature in presence of two witnesses.
